To all whom it may concern.-

Be it known that I, J AMES GARTON BoWER the Younger, a subject of the Queen of Great Britain and Ireland, residing at Norwich, in the county of Norfolk, England, have invented Improvements in Machinery for the Manufacture of WVire-Netting, of which the following is a specification, and for which foreign letters patent have been granted as follows: in France September 3, 1892, No. 224,121; in Belgium September 3, 1892, No. 101,225, and in Germany October 8, 1892, No. 68,311.

This invention has reference to improvements in machinery or apparatus whereby wire netting having meshes of different sizes combined in one so-called continuous width and of the improved kind hereinafter described and shown can be manufactured in an economical and practically continuous manner. For this purpose I provide a separate and independently operated pair of slides with half pinions for each different size of mesh required to be included in the one width of netting, and for the purpose of uniting. the netting of one'size of mesh with the netting of another size of mesh,I cause one slide of each of two adjoining pairs and adapted for producing two sizes of 1nesh,to assume relative positions in which a half pinion of the set for producing the one size of mesh, will be opposite to and will coincide with a half pinion of the set for producing the other size of mesh and in this way by a rotary movement of these two half pinions about an axis which is their common axis for the time being, the wires of the two sets of meshes are united.

Machinery to operate on the principle just above set forth may be variously arranged.

Provision is made for supporting each of the half pinions referred to when there is no other half pinion or slide opposite to it. This may be done in several ways, for example by means for lovers, cams or other supports.

. In the accompanying drawings, Figurel is a front elevation. Fig. 2 is a plan; and Fig. 3is an end elevation of a wire net making machine, constructed according to this invention. Fig. 4 is an enlarged elevation of the middle pinions in certain slides B and D hereinafter referred to, at the junction of the two meshes. Fig. 5 is a section through the slides model.) Patented in France September 3, 1892. No. 224,121; in Belgium September 3, 1892, No. 101,225, and in Germany October 8. 1892, No. 68,311.

at the'line 00 y Fig. 1, showing two. half pinions in the positions they assume at the union of the two meshes. Fig. 6 is a plan of the slides-and pinions in their second position. Fig. 7 is a plan of the slides and pinions in their third position. Fig. 8 is a plan of the slides and pinions in their fourth position. Fig. 9 shows a piece of wire netting of two different meshes, such as can be produced in my improved machine.

A A are standards connected by stays and forming the framework of the machine for supporting the moving parts.

B B are slides carrying half pinions O C respectively for forming the larger mesh of netting, in a manner well understood.

D D are slides carrying half pinions E E for forming the smaller mesh of netting. Each of these half pinions 0, 0 E, E has a hole 0 or E bored through it for the passage of a wire (A*, Fig. 1) from the corresponding coil or bobbin.

F is a rack for imparting rotary motion to the pinions 0' 0 G is a rack for imparting rotary motion to the pinions E E H is a stay bolted between the main standards A A and formed with a V shaped sliding surface for supporting two sliding frames I K that operate the racks G and F respectively. These .two frames I, K are connected with the racks G, F respectively by connecting pieces J J? that work through openings in the backs of the slides B and D.

M is a connecting rod for operating the frame I.

N is a disk fixed on the shaft X and provided with a crank pin N for imparting mo tion to the connecting rod M.

O is a cam plate formed with a cam groove 0 s t w a; for operating the frame K through a cam roller 19 which works in the said cam groove. p

P is a roll provided with pegs or staples (not shown) for drawing up the netting during the process of manufacture. This roll is omitted from Fig. 2 in order that the parts of the machine below it may be more clearly seen.

Q is a spindle on which the finished netting is wound.

R is a lever for imparting longitudinal motion to the slide D from the slide D. R is studs;

S is a stay fol-supporting the slides B and D. T is a stay for supporting the slides B I). U U are plates bolted to the stays 'l and H respectively for supporting and inaintaining the two sets of slides in their correct positions. DIIS V' are guide pieces bolted on the slides WV W WV W are adjusting blocks f p ing theslides B, B and D D in their correctpositions.

Y is a shaft for rotating the cam 0.

Z is a fast pulley by which motion is imparted to the machine.

Z i is a loose pulley.

a is a fork shaped piece (hereinafter called a fork) for supporting the innermost half pinion E' when unsupported by a half pinion or slide opposite to itas shown in Fig. 7.

b is a lever for operating the fork a. It is fixed upon a rock shaft 15* to which is fixed another lever arm I) connected by a link 6 to a lever 12 that is pivoted at y and carries at its free end an antifriction roller 0.

d is a cam arranged to act against the roller 0 and impart the necessary irregular motion to the said levers and fork a. This cam is fixed upon a shaft e that is driven by bevel gearing f from a shaft g.

h is a bar fixed to the stay T and arranged between the inner ends of the slides B'Dfor the purpose of supporting the innermost half pinion c in the slide B when the same is unsupported by one of the opposite pinions or slide during the longitudinal motion thereof.

is a spring for quickly withdrawingthe fork a when the cam roller 0 is working on the smaller portion of the cam d.

m m are tubes attached to some of the half pinions and inclosing a coil of wire from which the other wire to form the netting is drawn as well understood.

0 is a roller under which the wires from the bobbins it pass to corresponding half pinionsz' The action of the machine is as follows: Assuming the slides, racks, half pinions, and connected parts to be in the positions shown in Fig. 2 and that motion is imparted to the gearing shown in pitch lines then the frames I and K will be simultaneously moved to the left by the action of'the connecting rod M and the cam roller 19 which will then be working in the portion 7* of the cam groove in the cam plate 0 and rotary movement will be thereby imparted to the pinions C C and E E by the racks F and G respectively. In the posi tion assumed the innermost half pinion C coincides with the innermost half pinion E the half pinion 0' being rotated by the rack F, and the half pinion E being rotated by the rack G. By this means the adjacent wires A* (Fig. 9) of the two portions of netting of different mesh are twisted together thereby uniting the said two portions of netting. When the pinions C (J and E E have made a given number of revolutions the two pairs of slides B B and D D are moved longitudinally each to halt the distance between the centers of the corresponding set of pinions so that. the slides and pinions then assume the positions shown in Fig. 6. The frame I is then moved to the right thereby imparting through the rack G a rotary motion to the pinions E E in the opposite direction to that to which they were previously rotated after which the slides D D are again moved longitudinally so as to cause them to assume the positions shown in Fig. 7 having then woven two complete meshes of the smaller size of netting. Duringthis last mentioned motion of the slides D D and rack G, the slides B B and the rack F are held stationary owing to the cam roller 19 at this time working in the circular portion which the position of the slides D D is reversed longitudinally so as to cause these slides to assume the positions shown in Fig. 8. When the slides D D commence to move into these positions the forka is quickly withdrawn from the said half pinion E owing to the cam roller 0 then falling on to the smaller portion of the cam d and the spring 70 operating the levers b b I) h While the frame I is moving to the left, the frame K is moved to the right by the cam roller 1) moving in the portion t' of the cam groovein the cam plate 0 thereby imparting rotary movement to the pinions 0 0 When this rotary motion has been completed, the cam roller 19 enters the circular portion w of the cam groove and all movement of the slides B, B and rack F ceases until the frame I has been again moved to the right and completed the rotary movement of the pinions E E The IIO mesh of netting will be co-axial with the innermost half pinion E which had previously revolved with the innermost half pinion E to form twists in the smaller mesh of netting.

' The two innermost half pinions O and E are then rotated as before to again twist the two ad acent wires A* together and unite the two portions of netting together.

The above described operations are repeated continuously during the working of the machine, the finished netting being drawn up by the roll P and wound on the spindle Q.

As will'be seen from Fig. 9 the larger meshes are not only wider than the smaller meshes but also much longer, there beingin the example shown two smaller meshes. to each larger mesh in the direction of the length of the netting. Such netting is much lighter in weight and consequently much cheaper than that heretofore made in which the meshes of diiferent sizes are of equal length and differ only in width and is quite as suitable for the purposes for which such netting is ordinarily employed.

If it be desired to form a greater number of twists in the larger mesh of netting, the innermost half pinion E might be constructed with a long journal so as to allow of its being moved in the direction of its axis, through the action of levers, cams or other methods, sufficiently to withdraw it entirely from the action of the rack G, (when it is in the position shown in Fig. 2) and allow it to be revolved with the half pinion C by the rack F.

What I claim is- V 1. In a machine for the manufacture of wire netting, separate and independent pairs of slides with half pinions spaced for each different size of mesh to be produced, one slide of each two adjoining pairs being adapted to assume relative positions in which a half pinion of the set for producing one size of mesh will be opposite to and will coincide with a half pinion of the set for producing another size of mesh, racks for operating said pinions, and mechanism adapted to reciprocate each pair of slides independently of the other pair or pairs, substantially as herein described for the purpose specified.
